Uncut Joe Camel matchbook covers(sheet)

I have two sheets of the matchbook covers of Joe Camel, Ive owned them since I was in middle school, and placed them into photo frames and til this day thats where they sit. Now I always see people trying to place the cut apart match books into a picture frame, trying to make them look good as possible. Ive never seen any other uncut sheets on the internet and im always looking to see them, so are they just collectable or a rare collectible find that i have. Can someone guide me in the right direction, I dont think ill ever get rid of them since im now 42 and kept them this long, and always was proud of them and they look cool too, its a part of history, as is the death of Joe Camel.
